Suppose a species of snake is living in a certain area. some of the snakes in the population are black and some are orange. over time, the area changes and the orange snakes have a harder time blending into the environment. this makes it difficult for the orange snakes to catch food. according to darwin’s theory of evolution, what will most likely happen to this snake population over time? 1)most orange snakes will survive and reproduce, passing on their traits to their offspring. few black snakes will remain in the population. 2)most black snakes will survive and reproduce, passing on their traits to their offspring. the number of orange snakes in the population will not change. 3)the black snakes will survive and reproduce, passing on their traits to their offspring. few orange snakes will remain in the population. 4)most orange snakes will survive and reproduce, passing on their traits to their offspring. the number of black snakes in the population will not change.

Red flowered snapdragons are crossed with white flowered snapdragons, producing all pink snapdragons in the f1 generation. what would you expect if you crossed pink with pink? 3/4, 1/4, 1/2 red, 3/4,/1/2,/1/4 pink,1/2, 3/4, 1/4 white

Where does all the water go? according to the environmental protection agency (epa), in a typical wetland environment, 39% of the water is outflow; 46% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem (reference: united states environmental protection agency case studies report 832-r-93-005). chloride compounds as residuals from residential areas are a problem for wetlands. suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found: outflow, 60.4; seepage, 73.7; remaining due to evaporation, 26.4; in the water volume, 46.8. (a) compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (round your answer to one decimal place.) mg/l (b) suppose the epa has established an average chlorine compound concentration target of no more than 58 mg/l. does this wetlands system meet the target standard for chlorine compound concentration? yes. the average chlorine compound concentration (mg/l) is too high. yes. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is too high.

In pea plants, the allele for inflated pod seed, i, is dominant over the allele for constricted pod seed, i. the punnett square shows a cross for this trait. which offspring will be homozygous dominant
